BlackTom AI · Accepted Answer

The prompt asks for the histological section that divides a specimen along its long axis, i.e., a longitudinal section. 
Option A: 'cross'—a cross section is perpendicular to the long axis, cutting across it rather than along its length, so this is not the described plane. 
Option B: 'oblique'—an oblique section cuts at an angle to the long axis, not specifically along it, so it doesn’t match the requested straight along-the-length division. 
Option C: 'transverse'—a transverse section is another term for a cross section, cutting perpendicular to the long axis; hence it is not the longitudinal plane. 
Option D: 'sagittal'—a sagittal section is a vertical plane that divides the body into left and right portions and is typically aligned with the long axis, but in histology the term used to describe a lengthwise cut along the structure is 'longitudinal'; sagittal is a specific longitudinal plane relative to the body, and may not be the general term the question intends. 
Option E: 'longitudinal'—this is the term that describes a section cut along the length of the specimen, i.e., parallel to its long axis. This matches the description precisely. 
In sum, options that refer to perpendicular cuts (cross, transverse) describe cuts across the length rather than along it, the oblique option describes an angled cut, and longitudinal (E) directly corresponds to slicing along the long axis; sagittal is a specific longitudinal plane but not the general term requested here.
